The ocelot, Leopardus pardalis, is a medium-sized Neotropical felid with a relatively wide geographical distribution. Across their range, ocelots exhibit clinal variation in pattern and color of pelage. Despite this variation, few aberrant genetic morphs have been documented. This record describes the first apparent leucistic variant for the ocelot: a white female with black markings that was treed on three occasions over a 3-year period in the transitional Chaco of western Paraguay.
